career after mba

We live life in extremes..Take the example of life at an MBA institute and an engg institute and you will understand the difference. Yesterday, we had a gyaan session with our tuchhas...The way they portrayed life after A left us dumbfounded. Is this what we are going to be in 2 years time? Did we really come to A for such a life? Disillusionment has set in and for me every career option seems to be closed after i talk to a person who has worked in that field..Atleast something should appeal me ..I hope it happens otherwise MBA will be an opportunity gone waste :((
